Abstract: This paper is a rcsult of our engaging to study for the hierarchic problem of group Pseudokobresia C. B. Clarke, Which we have used classical com- parative method in plant taxonomy as well as the news-system, the correlative system and distance-system of numerical taxonomy among sect. Pseudokobresia and some relative groups (genus Carex, genus Blysmus, and sect. Elyna, Sect. Kobresia, sect. Laxa, Sect. Hemicarex of genus Kobresia). The dendrograms have reflected that the group Pseudokobresia differs from the genus Kobresia, although it is nearer to the genus Carex and the genus Blysmus, all of them being dislike. Hence it is better to regard it to the rank of genus rather than as a section of Kobresia, and we are agreeing to the point ot view of H. A. lvanova.
